Day 4-8 Convective Outlook

...DISCUSSION...
Organized severe thunderstorm threat will remain low through the
medium range period.

Moisture/instability will be shunted offshore early this week before
return flow allows modified Gulf air mass to advance northward into
the lower Mississippi valley day4/Wed.  This northward advance will
be due primarily to a strong mid-level jet forecast to translate
across the southern Plains into the OH valley.  While deep-layer
shear will be more than adequate for sustaining organized
convection, weak lapse rates and forcing near the coast suggest any
convection that evolves along a progressive cold front will remain
sub-severe in nature.
